Students having trouble registering should e-mail the instructor and show up on the first day of class.
Our textbook is University Physics with Modern Physics, Volume 1, 13th Edition. ISBN 9780321898012 or 9780321733382. Make sure to get the 13th edition; the "Technology Update" doesn't matter, so get whichever you can find. Used books are an order of magnitude cheaper! You do not need the Mastering Physics "bundle"; it's easier to buy the Mastering license online (instructions with the first homework).
